Let me say I came from the OG EVO. I bought a 32GB class 10 sdhc card and with that phone write speeds were horrendous! I barely got 7MB/s.. read however was in the low 20MB/s range. I reformatted that same card for use in my new SGS3 16GB. I am now getting 9-10MB/s write and about the same read. Finally a phone that actually makes use of these faster sd cards!

Whats the biggest micro card this phone will support. Are 32gb / 64gb even made?
i ordered this 16gb one, if there are 32 or 64 i want to know too
Kingston Technology SDC2/16GB 16 GB microSDHC Class 2 Flash Card
At the moment the largest card is 16GB.
16g is the largest, but 32g is coming out soon. My guess is that they will be quite expensive and no word on speed. While the class (speed) is in write mode only, it does make a difference when using the camera or writing files to the card.
I got a Ridata 16gig Class 6 microsd three days ago and works great!

The largest Rhodium supports is 32GB.
SDHC specs out at 32GB max.
I think only a few companies make 16GB Class 6 cards. Transcend being one of them. I don't think you can get 32GB ones just as yet and no way you can get a Class 6 one anyway.

and i think before they release 32gb SDHC they'll go the SDXC way with 64 & 128gb model.
if you plan on getting a Transcend card for use with a GSM TP2, be careful. There have been reports of Transcend cards not working well with the TP2. I personally experienced it, when my Class 6 8GB card would randomly disappear from the phone, or when music would skip during playback. Switched to a Sandisk Class 2 8GB that came with my BB Storm, and haven't experienced a single problem.
And also, note that the Transcend card worked great in my BB Storm, BB Bold 9700, LG Incite and Samsung BJII before this. Nothing wrong with the card, just with the TP2.
16gb is the largest built. 32gb is the largest theoretical that sdhc supports. youll need sdxc for more than that. i wonder if rhodium will support this in the future. old htc devices (and samsung) that could only do regular sd that capped at 4gb could do sdhc with a rom/driver update. sdxc supports up to 2tb which will be interesting to see.
The 32g microsd is long over due. Every so often there will be a press release that the 32 will be release within the next month or so. The projected time frame will come and go. There was a PR stating that 64g was in the works.
if a 32gb microsd card is sold i will buy it. i have an 8gb and could get a 16gb surprisingly cheap but i wont buy a stop gap knowing a 32 might be out soon.
I just got my 16gb no name cheapie from hong kong micro sd card for my tp2 in the mail. I spent numerous hours setting it up with the programs I wanted on it music and such. I had used it for about an hour or so and all the sudden the phone went crazy.. somehow the card corrupted it self im guessing cause the phone no longer recognized it or anything on it.. I removed the card and put it in my card reader to my laptop nothing was on it but a mess of folders all with the name ".." I thought maybe I had done something wrong so I formatted it and tried again. same thing happened the next day. I now reverted back to my 8gb sandisk and havent had any problems with it.. I guess its a get what you pay for kinda deal. Maybe there is something I can do I would think flash memory is flash memory but I guess they have their diffrences. Just wanted to share my .02 on my experience I would like to get another 16gb because bigger is better but ill wait it out and see what is to come next.
Biggest MicroSD Card
Sandisk 64GB SDXC formatted Fat32 works.. recognised as 60871.23MB under Settings > System > Memory and by Total Commander File Manager.
I wasn't sure if this belongs in Q&A or in Accessories, so if it's wrong, please move.
I've been reading that a lot of other phones can't make use of a MicroSD card with higher than a Class 6 speeds.
Even if they have a Class 10 Micro SD card, it will only perform at Class 6 speeds.
But writing from computer to MicroSD card (in the phone) can reach Class 10 speeds.
I don't want to spend the extra money on a class 10 card, when it's only going to run at class 6 speeds.
Has anyone been able to find (for certain) that the Evo can make use of any class speeds above 6?
Thanks!
I really hate to bump my own thread, but...
Htc replied to my email.
They say the evo is only capable of reading at class 2 speeds even with a class 10.
Can anyone clear this up for me?
Thanks again.
My Evo made me Swype this from the XDA App.
I am in the same boat as you. I've been searching for an answer on many forums and have found many posts that indicate HTC support representatives testing the EVO up to a class 4 with success. . .
I've also read that people have major problems with 32GB cards.
I have done some personal testing with my EVO and Windows 7 ; assuming the Win7 file transfer screen are close to reliable....cough. I also have USB debugging enabled on the EVO.
Transferring 700MB file:
EVO Samsung class 2, 8GB card ~ 4.64MB/sec (write to card)
Adata class 6, 4GB card ~ 11.8MB/sec (write to card)
I don't have a class 4 card to test with.
Download SD Card Speed Test. My 16gb class 6 checks out as a class 6, and it all runs within the phone.
The only way to find out about class 10 is to have someone with a class 10 card run the test.
Yes the Evo can only as they said, Read at Class 2, however the big thing we are looking for are Write speeds. Which is why we use a higher class. I am using the Wintec 16gb Class 10 card, and i get 9mb/s write speeds to it. And it is also cheap, got mine for 29.99 from the egg.
What speeds should I be getting?
I bought a sandisk 16gb off Ebay. Figured it was safe being "sandisk" and all.
I am getting about:
6mb/s write
19mb/s read
Saw someone pose they got 3 write and 130 read...
can this also be ROM related? They were on magnolia I am on CM7.
It sounds like a reasonable number, I have an older SD card that writes at about 3.5mB/s.
Sounds like a standard Class 2 memory card. Check your uSD card, does it have a little number inside of a circle? If it doesn't it's more than likely a class 2 card.
They categorize most flash-based memory cards by "class" now, the higher the class, the faster the read/write speeds. They have them in multiples of 2's. I have a class 6 8GB microSD from Transcend that I use for my Nook Color and I get on average around 11.5MB/s write speed.
Definitely atleast a class 4. Class 4 is 4Mb/s read speed. The write speed is irrelevant.
I have a class 4 Sandisk as well and it reads at just over 6Mb/s. Not sure on write speed. It was definitely faster than 19Mb/s though. Did you test it using h2test to make sure its a legit card?
My 16 gb PNY class 2 card was getting too small so I decided it was time to upgrade. As far as I could tell the Vibrant doesn't actually support UHS cards, but since I'm only a couple months away I just got one anyway.
I tested the cards with CrystalDiskMark in two ways, via USB in the phone, and in my laptop with an older SD2.0 card reader. The only Android app I could find that did anything other than sequential reads was AndroBench, and I couldn't get it to point at the external card. I'm on ICS, not sure if that was complicating the issue. If anyone knows of an app that does random r/w operations, let me know.
Sorry for the PNY/AData confusion in the screenshots, the UHS-1 card is AData and the Class 2 card is PNY.
I dunno if I've just had a run of bad luck with external SD cards, but in two months I've lost 2 SD cards! One 32G Sandisk, and just today another Lexar 8G (cuz I couldn't afford another 32G).
But it just frys them to the point where they just don't read anymore. I even try putting them in a card reader in my PC, and no dice. All my pics, music files, nandroids gone. Stuff that I unfortunately didn't back up on my pc. (Kicking myself hard)
My question is, has anybody else been losing SD cards? And, is there a program or a method that could possibly salvage any of the files on them despite them not being read by any card reader?
Any help much appreciated. Thx

I had a 32GB Sandisk microSDHC class 10 konk out less than a month and chucked it to a bad card. Sandisk replaced it. Prior to that I had a 16 GB in it for months and those were fine.
I think in your case it's just the cards going bad. I think the Sandisk 32 GB microSDHC might just have a bad batch somewhere. I got it from Amazon.com.
Yeah I think you have a bad card also
I use a 32 gig class 10 on my evo shift and the S3 shoots it out of the water, and I've never had any problems with the sdcard on my shift
